Question

Freckles are a dominant trait in humans. Both of the girls have the genotype FF for freckles. If either one marries a man with no freckles, what are the chances that their children will have freckles? A) 0% B) 50% C) 75% D) 100%

Answer 1

Answer:

The correct answer is option D, 100 %

Explanation:

Freckles are a dominant trait in humans

The female partner has genotype = FF

The male partner with no freckles shall have genotype = ff

The cross between the above two is represented through a punnet square-  

F F

f Ff Ff

f Ff Ff

Thus all the offspring will have genotype Ff,  

Since the dominant allele is F . thus all the offspring would have freckles

Answer 2

D. The man's traits (ff) would be recessive and with one of the girls (FF), all their offspring would have the genotype Ff, meaning all the offspring have freckles.
